Carrion Luggage  Native to the Americas, the turkey vulture (Cathartes aura) travels widely in search of sustenance. While usually foraging alone, it relies on other individuals of its species for companionship and mutual protection. Sometimes misunderstood, sometimes feared, sometimes shunned, it nevertheless performs an important role in the ecosystem. This scavenger bird is a marvel of efficiency. Rather than expend energy flapping its wings, it instead locates uplifting columns of air, and spirals within them in order to glide to greater heights. This behavior has been mistaken for opportunism, interpreted as if it is circling doomed terrestrial animals destined to be its next meal. In truth, the vulture takes advantage of these thermals to gain the altitude needed glide longer distances, flying not out of necessity, but for the joy of it. It also avoids the exertion necessary to capture live prey, preferring instead to feast upon that which is already dead. In this behavior, it resembles many humans. It is not what most of us would consider to be a pretty bird. While its habits are often off-putting, or even disgusting, to members of more fastidious species, the turkey vulture helps to keep the environment from being clogged with detritus. Hence its Latin binomial, which translates to English as "golden purifier." I rarely know where the winds will take me next, or what I might find there. The journey is the destination. |
| This Bloomberg CityLab article is two years old, but climate change doesn't work that fast, so it's probably still relevant. While a fascinating exercise, the headline is a bit misleading. A Cross-Country Road Trip Where It's Always 70 Degrees  An updated map from climate scientist Brian Brettschneider provides year-long interior and coastal routes that span more than 7,000 miles. The misleading bit is the "always 70 degrees" thing (I'm giving the use of Fahrenheit a pass because the article is very clearly US-oriented). But there's no need to be too pedantic about it. For travelers in search of the perfect weather, a climate scientist in Anchorage, Alaska, has mapped out the ultimate US road trip where the temperature is always 70 degrees Fahrenheit. The maps included in the article clarify: the routes follow "70°F Normal High Temperature." His original trips span more than 9,000 miles coast to coast for the contiguous US and more than 13,000 with an Alaska stop — the latter also draws on data from Environment Canada. Why Hawaii was excluded is left as an exercise for the reader. Both of the new routes manage to stay below 8,000 miles, unless travelers opt for a “connector segment” that passes through Arkansas, Tennessee and Virginia in April. I'd recommend that segment. Nice scenery. As an avid mapmaker who has made thousands and thousands of maps typically focused on climate, he says it’s hard to know what part of his work will resonate with people. But the overlap between climate and the road trip caught fire. As I said above, it probably doesn't change much in two years. But over longer time frames, sure. Like the first time, Brettschneider says while making the map was a fun exercise, he won’t be making the trip, but he would be interested in hearing from anyone who is planning to do so. It sounds like something I'd do, even though I consider 70°F to be entirely too cold, but I have cats to take care of. |
| Today, from PopSci, evidence that the US is actually #1 at something other than gun violence and imprisonment: US ranks first in swearing ‘Some may find it disappointing,’ said the new study’s Australian co-author. I especially love how the article anticipates the Krakatoa-scale explosion of doubt coming from Down Under, and states right up front in the sub-head that one of the authors was Australian. While the headline filled me with great joy, as usual, I can't just take a headline's word for this shit. Congratulations, United States. The nation may lag behind in healthcare, education, and life expectancy, but Americans still reign supreme in at least one way—swearing like a bunch of drunken sailors. My father was very careful, as a sailor, to avoid getting too drunk or swearing excessively. While I respect that, I've traveled a different path. Linguists in Australia recently analyzed the Global Web-Based English Corpus (GloWbE), a massive database containing over 1.9 billion words from 1.8 million web pages across 340,000 websites in 20 English-speaking countries. Oh, so they're only talking about written works. It's entirely possible that Australia still has the top spot with spoken cuss words, so calm down, kangaroos. “Rather than being a simple, easily definable phenomenon, vulgarity proves to be a complex and multifaceted linguistic phenomenon,” Schweinberger and Monash University co-author Kate Burridge wrote in the journal Lingua. I know people like to say, "What's the big deal? It's just words." Yeah, well, if words are just words, there should be no problem with ethnic or religious slurs, right? No. Words have power. Yes, we give them that power. But the power is there. “Some may find it disappointing, but the research found the United States and Great Britain ranked ahead of Australia in terms of using vulgar language online,” Schweinberger said in an accompanying statement. Now, I can think of one possible reason why the results skewed the way they did: while, as I noted, words have power, they have different power in different cultures. It's entirely possible that, in the US and UK, we have a greater awareness of the base nature of certain words, so using them signals a breaking of a taboo. The taboo (which is a word introduced into English from Tongan by Captain James Cook, the same guy who was the first European to visit Australia) has different strength depending on location. One of the study authors offers a different hypothesis: “One possible explanation is that Australians are more conservative when they write online but not so much when they are face-to-face,” he said. “Australians really see vulgarity, swearing and slang as part of our culture—we’re very invested in it.” Well, then, I guess someone needs to do a goddamned follow-up study. Despite its limitation (focusing on writing rather than speaking), I find the study amusing. As with most studies of this nature, I wouldn't take it to be the Absolute Truth, but at least it's evidence that the US is actually best at something besides fucking everyone in the metaphorical arse. |
| From PopSci, modern alchemy: Refrigerator-sized machine makes gasoline out of thin air The Aircela acts like a mini direct air capture facility, sucking up carbon dioxide and then synthesizing it into real, usable gasoline for cars. When you run a gasoline-powered internal combustion engine, in ideal principle, the exhaust consists of nitrogen, carbon dioxide, and water vapor (in reality, of course, nothing is ideal, so you get other chemicals from incomplete combustion). So the idea that one could, with the proper setup and energy input, reverse this, doesn't seem completely farfetched. And yet, reading this article, every fiber of my being cried out "fraud." In 2022, transportation was responsible for an estimated 28 percent of all U.S. greenhouse gas emissions. The majority of those emissions came from everyday gas-powered cars. Put another way, nearly 3/4 of greenhouse gas emissions came from something other than transportation. Most Americans also still just aren’t interested in ditching their gas guzzlers to save the planet. But what if they didn’t have to? It wouldn't save the planet. At best, it would slow down the destruction. (Yes, yes, I know, "the planet will be fine." "Save the planet" really means "protect the biosphere.") That’s the alluring—if wildly ambitious—vision being presented by New York–based fuels startup Aircela. Earlier this month, the company announced it had created the world’s first functional machine capable of generating real, usable car gasoline “directly from the air.” The article is fairly recent, so the announcement would have been in May. Aircela’s new device, roughly the size of a commercial refrigerator, combines direct air capture (DAC) with on-site fuel synthesis to create gasoline using just air, water, and renewable energy. No fossil fuels, they say, are required. You know, it occurs to me that this technology (if it's real, which, to reiterate, I seriously doubt) could be used for more important things. The manufacture of ethanol, specifically. Aircela demonstrated the process, making gasoline directly from air, in front of a live audience in New York. David Copperfield once made the Statue of Liberty disappear in front of a live audience in New York. Also, alchemists used sleight-of-hand to "prove" to their patrons that they've turned lead into gold. Though most would describe this proof of concept as a “prototype,” company co-founder and CEO Eric Dahlgren takes some umbrage with that label. Sure, go against basic English word usage because it offends you. Is it in mass-production yet? No? Then it's a prototype. “We didn’t build a prototype. We built a working machine,” Dahlgren said in a statement. “We want people to walk away knowing this isn’t too good to be true—it actually works.” It's the first one. It's a prototype. Aircela’s device essentially functions as a compact, portable direct carbon capture facility (DAC) unit. Carbon capture generally refers to the practice of removing carbon dioxide from sources like smokestacks or fossil fuel power plants. Don't get me wrong; I'd love to be wrong. About this. But it really does sound like fakery. A spokesperson from Aircela told Popular Science that their machine is designed to capture 10 kgs of CO₂ each day. From that, it can produce 1 gallon of gasoline. The machine can store up to 17 gallons of fuel in its tank. Yes, we Americans can switch easily from one system of measurement to another even in the same paragraph. That's a superpower. In other words, at least in its current form, the device wouldn’t be capable of filling up a car’s tank with gas overnight. That doesn't seem insurmountable. If it's real. But okay, let's assume for a moment, for the sake of discussion, that it works as advertised, and it's possible to create and distribute a reasonably-sized and -priced machine that turns air into gasoline/petrol. Now, think about how large oil corporations would feel about that, and what lengths they might go through to stop it from cutting into their profits. At the very least, they hand over a few million dollars for the patent and then... sit on it. Cynical? Damn right I'm cynical. It's hardly the first time someone has claimed to pull a rabbit out of thin air. |
